debian使ってます。
助けてください。
DVDドライブにCDを入れてからmountしたいんですができません。
$ sudo mount -t iso9660 -r /dev/sr0 /media/cdrom
コマンドを実行するエラーが表示されます
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error

In some cases useful info is found in syslog - try
dmesg | tail or so.

$sudo dmesg | tailの結果がこれです。
